Universal Overhead Valve Spring Compressor

• Keep hands clear of fan, belts and pulleys since slight crankshaft rotation will occur • Tool maintains constant length as spring is compressed • Use with 901DD or 2992D Air Hold Fittings to keep valve in place • Caution: vehicle must be placed in park/neutral before applying air pressure, otherwise vehicle may move • Remove valve springs on most cars with overhead valves without removing the cylinder head • Offset jaws grip the valve spring in parallel compression
